MACOS Uses touch -mt to change file creation/modification time. Here is the script:

    #!/bin/bash
    FILES="/Users/shakirzareen/Desktop/untitledfolder/*"
    for f in $FILES         ## f = full path + filename
    do
        t="${f##*/}"            ##remove folder path from filename
        t2="${t//_}"            ##remove _ from filename
        t3="${t2%%.*}"          ##remove file extension part
        touch -mt "$t3" $f  ##set creation and modification time of file
    done
